About This Item
PC57.12.34/D4F, Sept 2009 is a technical standard for mounted, compartmental type, self-cooled, three phase distribution transformers rated 5 MVA and smaller. It addresses equipment intended for high voltage applications at 34.5 kV nominal system voltage and below, with low voltage up to 15 kV nominal system voltage. In power, energy and industry applications, this specification helps define a common basis for design, rating, and evaluation of distribution transformers.
About PC57.12.34/D4F, Sept 2009
This standard focuses on the requirements and performance expectations for compartmental, self-cooled three phase distribution transformers used in mounted installations. PC57.12.34/D4F, Sept 2009 is relevant where transformer design must align with defined voltage classes, cooling method, and power rating limits. It is typically used as a reference for engineering decisions involving construction, electrical characteristics, and acceptance criteria for smaller distribution units in utility and industrial service.
Where is PC57.12.34/D4F, Sept 2009 used?
PC57.12.34/D4F, Sept 2009 is commonly applied in distribution systems where mounted transformer equipment serves local loads and medium-voltage conversion needs. It is relevant to substations, utility distribution networks, and industrial facilities that use compartmental transformer arrangements within the stated voltage range. The standard may also support procurement and specification of equipment for projects requiring three phase transformers with controlled self-cooling and a power rating at or below 5 MVA.
Importance in practice
Using PC57.12.34/D4F, Sept 2009 helps create consistency in transformer specification, comparison, and testing across projects. For buyers, engineers, and operators, that can reduce ambiguity around ratings, cooling approach, and voltage suitability. The standard also supports safer and more predictable selection of equipment for distribution service, which matters when coordinating compliance, performance expectations, and long-term reliability. PC57.12.34/D4F, Sept 2009 is therefore useful for limiting risk in design and procurement.
